The 17251 Big Size AC Ventilation Fan is a large-size high-power industrial ventilation and heat dissipation fan with a specification of 172mm×150mm×51mm, designed for large heat generation equipment and large-space industrial ventilation scenarios. Compared with small and medium-sized cooling fans, this large-size fan has larger air volume, higher wind pressure, and stronger air circulation capacity, which can meet the high-intensity heat dissipation and ventilation requirements of heavy-duty industrial equipment and large factory spaces. Adopting universal AC voltage design, it is compatible with industrial and municipal power supply systems, with strong power stability and lasting working performance.

In terms of structural design, the 17251 large-size specification is specially optimized for industrial high-power heat dissipation scenarios. The widened and thickened frame structure improves the overall structural stability and bearing capacity of the fan, and can resist the strong vibration generated by high-power operation without deformation or displacement. The large-diameter impeller is made of high-strength aluminum alloy, which is sturdy and durable, not easy to deform after long-term high-speed operation, and has strong wind gathering capacity. The multi-blade curved aerodynamic design greatly improves the air intake and exhaust efficiency, realizing super-large airflow output. The thickened fan body design optimizes the internal air duct structure, reduces air resistance, makes the air supply more concentrated and powerful, and can quickly dissipate the high heat generated by high-power industrial equipment.

In terms of power performance, the fan is equipped with a high-power industrial AC motor with full copper coil winding. The motor has strong power reserve, strong overload resistance, and can work continuously for 24 hours without failure. It has excellent high-temperature resistance, can maintain stable operation in a high-temperature working environment of 70 degrees Celsius, and will not cause motor burnout or speed reduction due to long-term high-load operation. The built-in high-precision silent bearings ensure smooth rotation of the impeller, reduce friction noise, and make the high-power operation process more stable and low-noise. At the same time, the motor has good voltage adaptability and can resist industrial power supply voltage fluctuations, ensuring stable airflow output in various power supply environments.

This 17251 large-size AC ventilation fan has a wide range of heavy industrial application scenarios, mainly used for heat dissipation of large industrial electrical cabinets, high-power inverters, welding machines, laser equipment, generator sets, and ventilation and heat dissipation of large factory workshops, equipment rooms, and warehouse spaces. For high-power industrial equipment with large heat generation and large-space environments with poor air circulation, this fan can form a strong air convection system, quickly discharge internal high-temperature hot air, reduce environmental temperature, avoid equipment aging and failure caused by long-term high-temperature operation, and improve industrial production efficiency. The whole machine has the characteristics of firm structure, stable performance, long service life, and low maintenance cost, and is a core ventilation and heat dissipation equipment for heavy industrial production and large mechanical equipment supporting.

8. Low Noise Cabinet AC Cooling Fan

The Low Noise Cabinet AC Cooling Fan is a special silent heat dissipation fan developed for indoor electrical cabinets, communication equipment cabinets, and precision control cabinets that require low-noise working environments. Aiming at the problem that traditional cabinet cooling fans have loud operating noise and affect the working environment and equipment operation accuracy, this product optimizes the motor structure, impeller design, and shock absorption system in an all-round way, realizing ultra-low noise operation while ensuring efficient heat dissipation. It is specially tailored for indoor office, laboratory, and precision workshop cabinet equipment heat dissipation scenarios.

The core advantage of this fan is its excellent low-noise performance. It adopts an optimized silent brushless AC motor, which realizes non-contact operation through electronic commutation, eliminating the friction noise and mechanical vibration noise of traditional brushed motors. The motor is equipped with imported high-precision mute bearings and high-temperature resistant silent lubricating grease, which makes the rotating resistance extremely small and the operation smoother. The fan impeller adopts a streamline silent blade design, which optimizes the blade spacing and curvature, effectively reduces air turbulence and wind cutting noise during air supply, and avoids the howling noise caused by uneven air flow. At the same time, the four-corner integral shock absorption structure and high-elasticity rubber shock absorption pads are used to completely isolate the vibration resonance between the fan and the cabinet, further reducing the overall operating noise, and the mute effect is far better than ordinary cabinet fans.

In terms of heat dissipation performance, while ensuring low noise, the fan does not reduce airflow and heat dissipation efficiency. Through fluid mechanics simulation optimization, the silent blade realizes the perfect balance of low noise and high air volume, which can efficiently circulate the air inside the closed cabinet, quickly take away the heat generated by circuit boards, power modules, and control components, and avoid local overheating and heat accumulation inside the cabinet. The fan adopts universal AC voltage design, with stable power output, constant rotating speed, and uniform air supply, which can maintain long-term continuous and stable heat dissipation operation.

In terms of safety and durability, the fan shell is made of high-grade flame-retardant and insulating materials, with high safety factor, anti-aging, anti-corrosion, and long service life. The built-in over-temperature and over-current protection function can automatically stop working in case of abnormal voltage and over-high temperature, effectively protecting the internal components of the cabinet equipment. This low-noise cabinet cooling fan is widely used in office electrical cabinets, communication base station cabinets, laboratory precision instrument cabinets, intelligent building control cabinets, and medical equipment cabinets. It not only solves the heat dissipation problem of cabinet equipment and ensures the stable operation of electronic components, but also avoids noise pollution to the working environment, creating a quiet and safe working environment for indoor work and precision equipment operation. It is a high-quality special heat dissipation accessory for indoor cabinet equipment.
